The vast majority of batteries are Lithium-ion, like most portable electronic devices, since it is the current technology with a better balance between energy density and price. The first electric bicycles worked with lead batteries that increased the weight of the bicycle to more than 40kg.Find more information about lithium forklift battery companies on our website.According to most manufacturers, the useful life of a Lithium-ion battery ranges between 500 and 1,100 complete charge cycles. In this sense, at a theoretical level, a cyclist who uses the bicycle daily to cover about 15km and performs the equivalent of two full charges per week could use the battery for about 10 years. In practice, but it must be taken into account that just as it happens with other devices, the battery suffers a slight wear annually regardless of the use that some manufacturers quantify in up to 5%, so it is not surprising that it has lost a significant part of its capacity after 4 or 5 years, despite continuing to function.What is the charging time of a battery?The time of a full charge varies mostly depending on the total capacity of the battery, its voltage and the transformer. As a guide, the charging powers range between 50 and 150W, and charging times between 2.5 and 4 hours. In any case, most manufacturers provide this information. Once the charge is complete, most transformers stop consuming so there is no problem leaving the battery charging overnight.How much does a battery weigh?Higher capacity batteries also weigh more, with differences that can reach 3 or 4 kg. In this sense, the most recommended is to adjust the size of the battery to the type of majority use that you want to make of the bicycle.What maintenance do I have to do to the battery?We leave you some maintenance tips, but we recommend consulting the instruction manual provided by each manufacturer to know more precisely what care each battery must receive.Before the first use, charge it up to 100%, as long as it is not fully charged from the factory.Frequently charge the batteries without waiting for them to discharge completely. You don't have to do it after each use, but keep in mind that the battery works a little better when it is above 50%.Always store batteries in dry and ventilated places at a temperature between 10 and 30 °C. During the winter, when it is very cold, it is recommended to store the batteries indoors if the bicycle is parked in a garage or storage room.If you plan not to use the battery for a long time, the ideal is to leave it with a charge level between 50 and 60%, neither very empty nor fully charged. In addition, a full charge should be carried out at least every 3 months.For more information - https://www.forkliftbatterymanufacturer.com/
